Five dimensions that matter most when picking between the two. Pricing and setup time are the biggest gaps.
Two minutes is what it takes, start to finish, screen-recorded, no edits.
Signivo is a centralised email signature manager built for teams on Gmail and Outlook. Your Google Workspace or Microsoft 365 admin connects your entire directory once: names, titles, departments, photos, the lot. After that, the person in charge of Signivo edits and publishes consistent, on-brand signatures across your organisation. There's one plan with all features included. Signivo is EU-hosted in Germany.
Built in 2026 by a small team that had spent years frustrated with the choice in this category: enterprise platforms with week-long rollouts on one end, hobby tools with no governance on the other. Signivo is the missing middle, fast enough to be live in minutes, structured enough to run an organisation on. No forced sales process, no implementation project, you start on your own and involve IT only where it makes sense. Support is AI-powered live chat plus direct access to the product team, with a guaranteed response within one business day.
Opensense was founded in 2013 in San Francisco as SenderGen, rebranded to Opensense in May 2018.
The product targets large marketing and IT teams, with banner A/B testing and CRM-based ABM targeting. On compliance it covers CAN-SPAM, CASL and CCPA, and it runs SOC 2 Type II audited operations. Trade-offs: the $350/month minimum excludes small teams, a service plan is required on top of every per-user tier, and certain features such as CRM integrations and recipient-based targeting require the highest licence tier.
Opensense is a San Francisco-headquartered, enterprise-grade signature, banner-marketing and compliance platform with deep CRM integration and a $350/month entry minimum. Signivo covers Google Workspace and Microsoft 365 with flat-rate pricing, EU-only hosting in Germany and a two-minute setup. Pick Opensense for ABM-driven enterprise marketing at scale. Pick Signivo for Google Workspace or Microsoft 365 teams that want EU residency and predictable per-user pricing.
Six dimensions, zero hand-waving. Who excels at what.
Signivo: One flat per-user rate, all features, no minimum spend. 1 EUR per user per month, or 10 EUR per user per year when billed annually.
Opensense: Three tiers (Signature, Pipeline, Complete) starting at $1, $3, and $5 per user per month respectively, all with a $350/month minimum plus required service plan. Banner scheduling and targeting sit in Pipeline; CRM integrations and advanced ABM targeting sit in Complete. Microsoft 365 GCC High adds a $2 per-user surcharge.
Information gathered from each vendor's website. Facts and figures may be outdated.
Signivo: On Google Workspace, an admin connects the tenant once and the directory syncs automatically. On Microsoft 365, an admin grants Signivo access in Entra ID and rolls out the Signivo Outlook Add-in centrally. Either way, minutes of admin time, not an IT project.
Opensense: Deploys via the Microsoft 365 Integrated App, which IT pushes from the Microsoft 365 admin portal. On that path there are no mail routing, DNS or SPF changes; the server-side path uses a transport rule, and the Google Workspace smart-host path needs DNS changes. Opensense puts deployment at 45 minutes.
Step by step, per platform: setting up Signivo in Microsoft 365 or in Google Workspace.
A like-for-like view of the capabilities Microsoft 365 marketing teams compare in 2026.
Signivo: Google Workspace via directory sync, Microsoft 365 via the Signivo Outlook Add-in. Opensense: Deep integration with Microsoft Entra ID, Exchange Online, Google Directory, Salesforce, HubSpot, Marketo, Pardot, Eloqua and Microsoft Dynamics.
The permissions an admin grants Signivo are written out for Microsoft 365 and for Google Workspace.
Signivo: AI-powered live chat, plus direct access to the product team with a response within one business day, regardless of your licence tier. Which we don't have anyway.
Opensense: Dedicated US-based phone and email support, named Customer Success Managers, plus an included custom design service that covers up to 5 signature templates per year.
Signivo: EU-hosted in Germany. GDPR compliant.
Opensense: Hybrid cloud built on AWS, Google Cloud, Microsoft Azure and bare-metal SOC 2 Type II data centres. US data centres by default with optional EU, Asia and Australia residency. Emails are processed only in volatile memory. SOC 2 Type II audited annually, with Microsoft 365 GCC High support.
Not every company is a Signivo company, and that's fine. Here's the clearest way we can put it.
Three steps, a couple of minutes. No consultants, no migration fees.
Ask your Opensense CSM for an HTML export of every active signature template and a CSV of your current banner schedule (campaign, dates, target segment, CTR). Re-create the static templates in Signivo first, then upload your banners to the Signivo banner library and set how long each one runs.
One approval from your Google Workspace or Microsoft 365 admin. Your colleagues' details flow in on their own from the company directory. A few clicks and you are connected to Signivo.
Upload your templates, or pick from our library, and publish company-wide in one click. Older signatures are overwritten.
Set up in 2 minutes. And if you still need convincing, scroll this page again.
